Compatible replacement kit for BX900R

This kit supplies two 12V7A sealed lead-acid batteries fused together as a direct replacement for the APC RBC5 pack used in the Back-UPS XS 900 R. It is built for high-rate discharge and long-duration backup so the UPS can keep connected equipment running during outages. Factory-fresh cells and comprehensive installation instructions are included.

Suitable for owners of the BX900R needing

The pack reuses the existing wiring harness, so no soldering or connector changes are required. Buyers whose UPS uses a different battery count, voltage or form factor cannot use this kit and should verify their model before ordering.

Two 12V7A cells deliver the rated runtime

The combined capacity matches the original specification, providing the same headroom for typical desktop, networking or point-of-sale loads. Runtime will fall short for heavier server arrays or extended-duration requirements beyond the design load.
